granularity value. For example, if you specify only -g ILM:256, the -g CLM:128 is implied
where 128 is the vPars default granularity value.
Memory: Notes on vPars Syntax, Rules, and Output
Memory: CLI Rules for Dynamic Migration of Memory
Note the following CLI (Command Line Interface) rules for online migration of memory and CPUs
while the target partitions are up. Note that because the following applies only to online migration
(in other words, where the target partition is up), it does not apply to the vparcreate command,
where the target virtual partition should never be up during the vparcreate invocation.
• In the same command, you cannot have an online addition and online deletion. For example,
the following are illegal:
◦ keira1# vparmodify -p keira2 -a cpu::2 -d cpu::1
◦ keira1# vparmodify -p keira2 -a mem::1024 -d mem::512
You must specify each change on a separate command line. For example, the following are
allowed:
◦ keira1# vparmodify -p keira2 -a cpu::2
keira1# vparmodify -p keira2 -d cpu::1
◦ keira1# vparmodify -p keira2 -a mem::1024
keira1# vparmodify -p keira2 -d mem::512
• In the same command, you cannot make changes to both memory and CPU. For example,
the following is illegal:
◦ keira1# vparmodify -p keira2 -a cpu::2 -a mem::1024
• In the same command, you cannot make changes by both address and ILM or both address
and CLM. For example, the following are illegal:
◦ keira1# vparmodify -p keira2 -a mem::1024 -a mem:::0x40000000:256
◦ keira1# vparmodify -p keira2 -a cell:6:mem::1024 -a
mem:::0x40000000:256
• In the same command, you can specify both ILM and CLM changes. For example, the following
are allowed:
◦ keira1# vparmodify -p keira2 -a mem::1024 -a cell:6:mem::1024
• In the same command, you can migrate both base and float memory. For example, the following
are allowed:
◦ keira1# vparmodify -p keira2 -a mem::512:b -a mem::512:f
◦ keira1# vparmodify -p keira2 -a mem::512:b -a cell:0:mem::512:f
-a cell:2:mem::1024
Memory: Allocation Unit Notes
• The default memory assigned to a virtual partition is 0 MB, so you need to specify enough
memory for your applications and the operating system. See the Installation and Update Guide
for your OS and the nPartition Administrator’s Guide for your server.
• The unit for the specified size of memory for the vPars commands is megabytes; parmodify
uses gigabytes.
